Abstract
A U-shaped groove portable water level flowmeter includes a canal connection device and a water level flow ruler, wherein the canal connection device includes a U-shaped canal with a set standard section, a water level flow pipe and a communicating pipe; the water level flow pipe has a sealed bottom end, and is provided with a seal cover at the upper end and communicated with the U-shaped canal through the communicating pipe; the water level flow ruler includes a ruler body with water depth H graduation marks and flow Q graduation marks on the two sides respectively, and a test paper; the ruler body is vertically provided with a test paper slot at the middle part; the test paper is installed in the test paper slot; and the water level flow ruler is installed in the water level flow pipe communicated with the U-shaped canal and compacted by the seal cover. The U-shaped groove portable water level flowmeter solves the difficult problem that the plain irrigated area is lack of efficient metering equipment for agricultural canals with the U-shaped canal slope smaller than 1/5000, has low cost, is durable, portable, convenient for installation, simple to operate, and reasonably designed as being used once inserted, and has the structure technical parameters meeting requirements of water metering equipment at irrigated area proved by the field tests at the irrigated area, high water metering precision, and higher popularization and application values.
Description
Technical field
The utility model relates to agriculture irrigated area water measure equipment, particularly relates to being fit to the Plain Irrigation District channel than the U-lag formula stage-discharge meter that falls less than 1/5000.
Background technology
The irrigation water inadequate resource has become the key factor of restriction agricultural development, and water-saving agriculture is the inevitable choice of the future of agriculture development, and its center is to reduce water yield waste, improves WUEL.The irrigated area water gaging can calculate the water source timely and accurately and introduce the canal system and the water yield of distributing to channels at different levels and each water unit; Can analyze the water delivery loss of channels at different levels in view of the above; With transformation on economy of water cousumption foundation is provided for continuing of irrigated area is supporting; Can accurately estimate the water-saving result of various measures, promote the popularization of water saving experience greatly.
The irrigated area water gaging is that the irrigated area provides foundation by the irrigated area charge to charging by water consumption, is to promote water saving through economic means, carries out the pacing items of quota water supply, excess price markup.Simultaneously can also avoid broad irrigation to a certain extent, reduce seepage effectively, rationally control underground water table, alleviate the secondary salinization of soil of soil, can reduce nitrogen phosphorus leaching loss simultaneously, alleviate widespread pollution from the overuse of fertilizers and pesticides in rural area and carrying capacity of environment.
The irrigated area canal water gauging only is metered into this one-level of lateral canal, adopts below the lateral canal and presses the equal shunt volume of area, and main cause is that the field ditch number is many, lacks effectively and the low water measure equipment of cost.For scientific and reasonable metering mu water consumption, promote the development of water-saving irrigation technique, also corresponding support equipment should arranged aspect the field ditch water gaging.It is little that Plain Irrigation District field ditch principal feature is that the channel ratio falls, and is generally 1/5000～1/10000.The existing water measure equipment that is fit to the U-shaped canal water gauging in " irrigation canal system water gaging standard " like para-curve aditus laryngis flume and measuring flume with straight wall, is applicable to that the U-shaped channel is minimum than reducing to 1/1500, can't use in Plain Irrigation District.Be scientific and reasonable metering mu water consumption, promote the development of water-saving irrigation technique, seem particularly important in the research and development of field ditch water measure equipment.
The utility model content
The technical matters that the utility model will solve lacks effective dose wetting system problem in order to solve the Plain Irrigation District channel than the U-shaped channel that falls less than 1/5000, and the portable stage-discharge meter of a kind of U-lag that provides.
The technical scheme that adopts is:
The portable stage-discharge meter of U-lag is made up of channel coupling arrangement and stage-discharge chi.Described channel coupling arrangement comprises U-shaped channel, stage-discharge pipe and the communicating pipe of the standard section of a setting.The bottom sealing of stage-discharge pipe, the upper end is provided with capping, and said stage-discharge pipe is through being communicated with the U-shaped channel communicating pipe.Described stage-discharge chi comprises that both sides are respectively equipped with chi body, the test paper of depth of water H scale mark and flow Q scale mark.Chi body central longitudinal is to being provided with the test paper slot, and test paper is inserted in the test paper slot.In the stage-discharge pipe that described stage-discharge chi is put into the U-shaped channel is communicated with, and compress with capping.
The chi body of above-mentioned depth of water H scale mark and flow Q scale mark, its depth of water H scale unit is cm, flow Q scale unit is L/S.
Above-mentioned stage-discharge pipe and the rectangular tube that communicating pipe is 40 * 30mm.
The above-mentioned communicating pipe inlet end that is connected with the U-shaped channel is provided with screen pack.
The utility model has solved the unmeasurable difficult problem of Plain Irrigation District field ditch U-shaped channel; It is low, durable, portable, easy for installation, simple to operate to have cost; Plug and play is reasonable in design, and its structure technology parameter all satisfies irrigated area water measure equipment requirement through the irrigated area site test; The water gaging precision is high, has higher popularization and application values.

Embodiment
The portable stage-discharge meter of U-lag is made up of channel coupling arrangement and stage-discharge chi 5.Described channel coupling arrangement comprises U-shaped channel 1, stage-discharge pipe 4 and the communicating pipe 3 of the standard section of a setting.The sealing of the bottom of stage-discharge pipe 4, the upper end is provided with capping 6, said stage-discharge pipe 4 is through being communicated with U-shaped channel 1 communicating pipe 3, communicating pipes 3 inlet end establish screen pack 2, stage-discharge pipe 4 and be the rectangular tube of 40 * 30mm communicating pipe 3.Described stage-discharge chi 5 comprises that both sides are respectively equipped with depth of water H scale mark 8, unit is that cm and flow Q scale mark 7, unit are chi body 9, the test paper 10 of L/S.Chi body 9 central longitudinal are to being provided with the test paper slot, and test paper 10 is inserted in the test paper slot, are used for showing the depth of water in the channel coupling arrangement.In the stage-discharge pipe 4 that said stage-discharge chi 5 is put into U-shaped channel 1 is communicated with, and compress the portable stage-discharge meter of formation U-lag with capping 6.
During measurement, water flows through U-shaped channel 1, and water was got in the stage-discharge pipe 4 by communicating pipe 3, directly the depth of water was presented on the test paper 10, and its test paper has indiffusible characteristics in the 1min.Theoretical derivation by the depth of water calculates corresponding flow, looks into flow Q mark according to depth of water H mark correspondence, draws U-lag water-carrying section flow: L/S.
